The LTC®4215/LTC4215-2 Hot Swap™ controllers allow a board to be safely inserted and removed from a live backplane.

Using an external N-channel pass transistor, board supply voltage and inrush current are ramped up at an adjustable rate.

An I2C interface and onboard ADC allow for monitoring of load current, voltage and fault status.
